=== Testing LaTeX ===
We can have inline maths, like $n \cos y$ and $n \sin t$.

$y_1 = y_2$

In other words again, $x^2+(b/a)x=(x+(b/2a))^2-(b/2a)^2$.

I'm trying to force this to look like a multline environment, with no luck $\ldots$

$Q^{n,m,k} = \big( P_2(y_1,y_2,y_3)^n P_3(y_1,y_2,y_3)^{2m+3}
+ P_2(y_4,y_3,y_2)^n P_3(y_4,y_3,y_2)^{2m+3}$
&nbsp; &nbsp;   $ \quad + P_2(y_3,y_4,y_1)^n P_3(y_3,y_4,y_1)^{2m+3}
+ P_2(y_2,y_1,y_4)^n P_3(y_2,y_1,y_4)^{2m+3} \big)$
              $ \times \big(
P_4(y_1,y_2,y_3,y_4)^k + P_4(y_1,y_3,y_2,y_4)^k + P_4(y_1,y_4,y_2,y_3)^k \big).$

Try \begin{align} and \end{align}.

'''''test'''''<comment thread="517" />

I'm just adding something to see whether it works, and then to see whether I can manage an inline comment.

I'm doing the same. I'm adding this sentence, so that I can then comment on how deeply unimaginative this sentence is.<comment thread="24" />

[note section contributions wanted]Having some more examples here would really help. In particular, we could use an example that uses unimaginary numbers.

[QUICK DESCRIPTION]

[note article incomplete]This article is missing large parts of what is required of a Tricki article.
[/note]<comment thread="13" />

Another commenting test.

===A test===

This is to see whether I can do nested "add"s.

[add] Article 1 {{[add] refers to Article 2 {{which in turn refers to Article 3!}} [/add]}} [/add]

Hmm ... seems not to work.  But it should work now!

Wow -- that's fantastic. OK I'll see how many levels of nesting there might be.

[add] Article 1 {{[add] refers to Article 2 {{[add] which refers to Article 3 {{which refers to Article 4!}} [/add]}} [/add]}} [/add]

Thanks Alex -- I've actually got a use for this ...

What about hyperlinks inside "add"s?

I wonder whether [add] I could {{add a [[how to use martingales]] link here}} [/add]

That's fine.

Another experiment.

In the middle of a list, I want [add] Article A {{
*with a list
**with headings and subheadings
**and more subheadings
*and another heading or two
**and subheadings [[with links]]
**and so on
}} [/add], Article B, etc.<comment thread="454" />

The next experiment is intended to demonstrate the lists/[add] bug. At least on my Mac, each time I expand and collapse again, I end up with a new set of arrows.

*[add]Article A{{
**has Article B as a subarticle}}[/add]

As far as I can tell, I'm copying the markup directly from what it says in the formatting page, but it isn't working.
